' This invention relates" to a tool for apply- 7 ing hairpin clips to angle carrying bars, as

. the furringirons, and leg portions used in building constructlons.

In building constructions, it is common practice to support furring irons by angle carrying bars, which, in turn, are'supported by togglehangers which depend fromthe' floor construction. The angle carryingfbars are attached to the toggle hangers by rivets or the like, and are for the purpose ofcarrying the furring irons which extend in angular relation to the angle carrying bars, and relatively close together. This arrangement leaves a space b tween the i'urring irons an the lower surface of the floor. It has been the practice to secure theflfurring irons to the angle carrying bars by hairpin clips which include bight portions adapted to embrace adapted to be bent over the upper edges of the angle carryingbars. i r The application of these hairpin clips has been somewhat difiicult in the past, and it has been common practice tofirst slipa hairpin erable extent. However,

clip over the Ifurring iron after thelatter has been put in place against the lower sides of the angle carrying bars, so that the bent ends or legs of the hairpin. clip overlie the upper edgeofthe angle carrying bar. To bend these extended ends or legsdownwardly toernbrace the angle carrying bar and to form, in eflect, hooks over the upper'edge of the same, apr ac- =tice has been'resorted to which includes the placingof a small pipevoverthese ends or legs and bending them down asfar as possible withtheuse of thispipe. To vget the maximum action of this pipe, it'hasbeen customary to bend theipipe-at anangle so that it .will conta ctwith the furring irons or with the angle carryingbaronly afterthelegs of the hairpinclip have; beenibe'nt to aqconsidit has not been possible to bendtheselegs by me ns of this pipeinto their finial position, and the practice has been, after removal of the pipe, to com plete the bending by striking the legs with a hammer. ;f

The above pract-ice has been attended by many disadvantages. The relatively small space between the floor and the furringiron's 1931.; Serial No. 531,75 I afiords an inconvenient working space, and thelre'sulthas been that the. hammering down of the legs not only consumes acomparatively great amount oftime, but does not insure the clinching of the hairpin clip on the angle carrying bar in such position that the furrin'g irons will be held tightly and i'm mo'vably against the angle carryingbars. There are man other disadvantages incident to the use of the bending pipe and hammer.

The primary object of the present inventionrtherefore,

ing "the hairpin clips in such manner that all 1 of the above referred to disadvantagesljare overcome; r "I o .i

A more specific ob'ect of the present inventionis to provide a relatively light and simple form of tool which may be readily handled and manipulated, andby means o'f'which' the application of the hairpin clips will be greatly faci1itated.

'- The prese'ntinvention ,conslstsin the novel form, combination and arrangement of parts hereinafter more fully described, shown in theaccomp anyingdrawings and claimed.

In the'drawings": Figure 1 is a view, partly in side elevation and partly brokenaway and in section, showing a tool embodying the as it appears when in use preparatory to ilinching a hairpin clip on an angle carrying ar. w

i as 5 hairpinclips as it" appears beforebeing tension or end portion ported by the usual toggle hangers depending from the floor of the building. At the juncture between the legs 6 and the bight portion 5 of the hairpin clip, the wire is bent to form seats 8 which are adapted to engage over the upper edge of the carrying bar 7.

The present invention embodies an improved tool by means of which the legs 6 of the clip may be clinched into position or bent down against the inner face of the vertical flange of the carrying bar 7 as indicated by dotted lines in Figure 1, whereupon the clip will appear as shown in Figure 6. As shown, the present tool is of the plier type and em bodies a pair of handles 9 and 10, the outer end of the handle 9 being extended laterally and slotted as at 11, and the outer end of the handle 10 being pivoted to the handle 9 within the slot 11 as at 12. Formed integral with the outer end of the handle 9 is an angular inner jaw comprising an inwardly extending portion 13 and a laterally extending free end portion 14, adapted to respectively flatly en gage the outer faces of the vertical and horizontal flanges of the angle carrying bar 7 as shown in Figure l. The outer face of the jaw portion 13 is provided with a central longitudinal rib l5, and the free end portion 14: of the inner jaw is narrower than the portion 18 and of a width similar to the width of the rib 15. The clip is thus adapted to be sprung onto and to frictionally engage the inner jaw of the tool to be carried by the latter, the bight portion 5 of the clip embracing the jaw portion 14 and engaging opposite sides of the rib 15 of the jaw portion 13 as shown clearly in Figures 1, 3 and 4. In this way, the clip may be applied to the tool, and then the tool may be positioned to properly set the clip in place relative to the carrying bar 7 so that it may be readily clinched without one hand of the operator being used to position and hold the clip in place.

The tool further embodies a lateral ex- 16 on the outer end of the handle 10 having a transverse platelike outer jaw 17 formed integral with the free end thereof. The outer jaw 17 is arranged to project inwardly so that its inner transverse edge will contact with and extend across the legs 6 intermediate the ends of the latter and a distance laterally of the vertical flange of the carrying bar 7 as shown in Figure 1. It will be further noted that when the jaws are separated, the handles 9 and 10 will also be separated, so that upon pressing the handles together the outer jaw 17 is brought downwardly and inwardly so as to effectively clinch the legs 3 against the inner face of the vertical flange of the carrying 7 as indicated by dotted lines in Figure 1. Due to engagement of the outer jaw 1'7 with the intermediate portions of the legs 6, the clip will be effectively clinched so that they need not be finally forced down by hammering or the like.

After the clip has been applied, the jaws may be separated and the jaw portion 14 readily withdrawn from the bight portion of the clip.

While we have described a particular embodiment of our invention, it is to be understood that minor changes may be made within the spirit and scope of the invention as claimed.

What we claim as new is:

1. A tool for applying hairpin clips to angle carrying bars including a pair of handles pivoted together, an angular inner jaw integral with one of said handles and embodying an inwardly extending portion and a laterally extending free end portion adapted to respectively flatly engage the outer faces of the flanges of the carrying bar, and, a transverse plate-like outer jaw integral with the other handle and arranged to engage and extend across the intermediate portions of the legs of a hairpin clip when the latter is disposed with its bight portion embracing the free end portion of the inner jaw.

2. A tool for applying hairpin clips to angle carrying bars including a pair of handles pivoted together, an angular inner jaw integral with one of said handles and embodying an inwardly extending portion and a laterally extending free end portion adapted to respectively flatly engage the outer faces of the flanges of the carrying bar, and a transverse plate-like outer jaw integral with the other handle and arranged to engage and extend across the intermediate portions of the legs of a hairpin clip when the latter is disposed with its bight por-.

tion embracing the free end portion of the inner jaw, said inwardly extending portion of the inner jaw having a central longitudinal rib adapted to be engaged at opposite sides by the bight portion of the clip, whereby the clip may be held by the tool substantially against the carrying bar.
